RPMT 1204EN AH725 RPMT indexable insert for milling — round, with central hole, by Tungaloy

The RPMT1204EN AH725 is a round indexable insert engineered for general‑purpose milling in Tungaloy systems, combining a PVD‑coated carbide grade with a breakout‑resistant geometry for reliable performance across steel and stainless steel applications.

• PVD-coated carbide AH725
• Universal, breakout-resistant for steel & stainless
• Round insert 12 mm, 4.76 mm thickness
• Central hole; cylindrical pocket + single-side countersink

Reliable machining across changing materials

The AH725 PVD‑coated carbide grade offers a balance between wear resistance and toughness, making it suitable when workpieces vary between steel and stainless steel. This universality reduces the need for frequent insert changes, supporting uninterrupted production and a consistent process window. The robust grade is particularly effective in smaller tools and in operations where process security is a primary concern, as the coating and substrate combination help maintain edge integrity under interrupted cuts and variable feeds.

Stable clamping and repeatable positioning for consistent results

The round shape with a central hole and a cylindrical pocket plus a single‑side countersink (40°–60°) provides secure mechanical location in compatible cutter bodies. With a diameter of 12 mm and a thickness of 4.76 mm, the design delivers consistent seat contact and repeatability during indexing. Correct matching of insert seat, geometry and cutter body in the Tungaloy system ensures minimal play, improved runout and predictable tool life, which directly benefits cycle‑time stability and reduces scrap rates.

Controlled chips and improved surface finish

The single‑sided chipbreaker is optimised for controlled chip formation during face, shoulder, slot, high‑feed and contour milling, limiting vibration and chip entanglement. Controlled chips and stable cutting forces contribute to a better surface quality and reduce secondary finishing work. Where applications demand a mix of roughing and finishing steps, the insert’s geometry aids in maintaining consistent dimensional accuracy and reduces the likelihood of built‑up edge on stainless steels.

Easy system integration and application flexibility

This insert forms part of a complete milling system comprising the cutter body, indexable insert, clamping screw and, if required, a shim. The 11° clearance angle supports positive cutting engagement and contributes to reliable chip evacuation. Given the standardised ISO designation and the specified hole style, the insert can be specified quickly for compatible Tungaloy tool families, helping to simplify inventory and procurement for production lines that require dependable, off‑the‑shelf performance.
